FEEDING DEVICE.

Original application filed July 9,1909, Serial no. 506,751. Divided and this application filed August 24., 1910. Serial No. 578,766.

To all whom it may concern: U

Be it known that I, JOHN J Demon, a subject of the King of Great Britain, residing at South Framingham, in the county of Middlesex and State of Massachusetts,

therefor, together-with means for supplying.

the eyelets or causing them to be supplied to said raceway, all as hereinafter set forth.

This invention is a divisional part offthe application filed by me in the United States Patent Oflicc, July 9th, 1909, Serial No. 506,751, for a patent on gang eyeleting machines.

The object of my invention is to provide an eyelcting machine with a feeding device for the eyelets, which is strong and durable, simple. in construction, consists of few parts easily assembled, is certain in action, and withal practicable and efiicient.

' Other objects will appear in the course of the following description.

I attain these objects by the means and mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a machine which embodies my invention in a practical form, most of the corresponding side of the casing being omitted or cut away so as to disclose the parts within, leaving portions of the frame work and the table .in section, and, Fig. 2, a rear elevation of said machine, without the driving pulleys or the belt shown in the preceding view.

Similar figures refer to similar parts in the two views.

The frame or more correctly perhaps the casing, which supports all and inclose's some of the operatingparts of the machine illus trated in the drawings, comprises side pieces 1 and 2, a base or floor piece 3 connecting such side pieces at the bottom,.=cross pieces-- 4 and 5 extending between said side pieces 2-, lugs (I pro ecting inward from each-of the side ieces from which a hood 7- projec'ts at t e front end of the casing.

9 is a work table.

t thefront of the machine is a vertically-movable slide 11. A main driving shit. 12 is journaled in the cross-pieces 4 and 5, and operates the slide 11 through'the medium of a suitable connecting-rod 15. The [slide 11 carries thelower sets one of which appears at 24; and above said lower sets, in asuitable supporting member on the hood 7, are the upper, fixed sets. one of which appears at 26. A gang raceway 42, to cooperate with the movable sets. is fastened on a bed-plate 43 mounted on a horizontally reciprocatinc carriage 44. The raceway 42, bed-plate 43, and supporting part of the carriage 44 for said plate are all inclined downwardly and forwardly, so that the eyelets will gravitate forward or toward the delivery end of said raceway. The bed-plate is held in place on the carriage 44 by means of a transverse rib 45 and two longitudinal ribs 46 on the bottom of said 'plate, said rib 45 engaging behind a transverse shoulder-t7 on said carriage and said ribs 4 6 entering suitable longitudinal slots in said carriage. The bed-plate is also bolted to the carriage at 48-48. Yielding stopsfone of which appears at 51, are provided at the front end of the raceway 42, the ofiice of which is to hold back the eyelets in the usual manner and for the usual purpose.

Depending from each side of the carriage 44 is a pair of lugs 54 in line with the corresponding pair of lugs 6, and each pair of these lugs 54 is mounted to slide on a horizontal rod 55 fast in the aforesaid corresponding pair of lugs 6. Mounted on a stud 56, depending from the center of the carriage 44, is an anti-friction roller 57 which enters a cam-groove 58 in a cam 59 tight on the main shaft 12 in front of the cross piece 5. The shape of the cam groove 58 is such that, as the cam 59 revolves, the carriage 44 is reciprocated through the medium of the roller 57. The movement of the carriage 44 for the raceway 42 is so timed relative to the movement of the slide ll for the lower sets 24, that said raceway is adthe side pieces, and a top connection between vanced into position ready to deliver eye- Patented Oct. 28, 1913.

lets to said sets while the latter are down, and is withdrawn from such position as soon as said sets have risen into the eyelets directly above, so as to clear the way for the sets and the eyelets thereon as said sets continue to rise. A suitable hopper 61 for eyelets is bolted at 62-62 on the bed-plate t3 at the upper, rear end. The raceway 42 receives its supply of eyelets from the hopper 61, a rotary agitator (not shown) being employed in the hopper to assist in feeding the eyelets to said raceway, all in the usual and well-known manner.

The eyelet-agitator driving mechanism consists of a gear 63 tighton the lower terminal of a revoluble agitator shaft, indicated at 127, in Fig. 1, which is journaled in the hopper 61 and the bed-plate 43, said gear being below said plate, a pinion 64: and a pulley 65 to which said pinion is attached and both of which are loose on a stud 66 projecting below said plate, two pulleys or idlers 67 on a horizontal shaft 68 mounted in an arm 69, a pulley 70 on the rear end of the shaft 12 and revolubly connected with a main driving pulley 71 loose on said shaft 12, and a belt 72 which passes under said pulley 70, over said idlers and around said pulley 65. The arm 69 extends longitudinally of the bed-plate 43, beneath the same, carries the shaft 68 at its rear end, and has its front end pivoted at' 73 to the carriage 14:; and said arm is supported back of its pivotal point on an eccentric or cam 74 tight on a stem 75 journaled in two lugs 76 rising from said carriage atthe rear end. The stem 75 extends from the lugs 76 out beyond the side 1, and has a handle 77 on its outer end to facilitate turning the same. The pulley 70 is held in place on the shaft 12 by a washer 78 and a bolt 79, the latter being tapped into the rear end of said shaft, and said pulley is rotatably connected with the pulley 71 by a pin 80 which projects from the inner face of'said pulley into said pulley 71. The pulley 71 is belted to a main or counter-shaft (not shown) and re volves during the entire time that the machine is in use, hence the agitator-driving mechanism described above revolves constantly and keeps the eyelets in the hopper 61 in a continual state of agitation so that a full supply of eyelets is insured to the raceway 42. The proper tension is put on the belt 72 by turning the stem and its cam 74 to swing the arm 69 up or down on its pivot 73, said belt being tightened or loosened accordingly'as the result of such action, since the distance between the axes of said pivot 73 and the shaft 68 is always the same regardless of the position of said arm, while the distance between the axes of said shaft and the shaft 12 changes when the arm moves. it suitable clutch, or clutch mechanism such as that disclosed in my aforesaid application, also in another divisional application filed on even date here with, and serially numbered 578,767, is employed to rotatably connect the shaft 12 with the pulley 71 and disconnect it therefrom, it not being desired to operate the movable sets and the raceway continuously.

The operation of the machine herein shown, so far as the present invention is concerned, will be fully understood from the preceding description and needs'no further explanation. 1

The manner in which the bedplate 43 is mounted on the carriage -14 enables me easily and quickly to remove the raceway 4E2 together withthe hopper 61 from the machine, when for any reason it becomes necessary or desirable to do so, by simply removing the bolts 48 and lifting said plate from said carriage, after first disengaging or disconnecting the belt 72; and the members can be as'readily reunited. The relative positions of the carrying members for the belt 72 are such that said belt and its operation are not materially affected by the reciprocating movement of the carriage 44:;

More or less structural and other changes may be made in my invention without departing from the nature thereof.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in an eyeleting machine, with a reciprocating carriage having an inclined top, of a raceway provided with a bed-plate removably mounted on said inclined top of the carriage, transverse engaging projections on said carriage and plate to hold the latter against endwise displacement in a forward direction, longitudinal engaging means, comprising a rib and groove, be-
